So, today, i built my first computer. it is in a fractal design define r4, with an asus p8z77-v deluxe mobo, 16GB gskill x series ram @2133, 2 GTX670SLI, ASUS dx soundcard, seasonic 1050W 80 plus Gold. i73770k, and two hard drives, one is a 256GB ocz vertex4, and the other is a 3TB seagate barracuda. now,my issue is that i got this computer running quite well, and it is extremely fast, BUT i cant get windows to recognize my HDD, i've looked in the BIOS but i cant figure out how to get it into the boot order, or anything. i can see the thing, when i look in the boot category in advanced mode, but it wont let me put it inot the main boot priorities, and windows cant see it either. anybody know of a solution that doesnt involve re-installing windows? Any help is very much appreciated!
